VALVE-OPERATING MECHANISM.

Specification of Letters Patent.

Patented Sept. 10, 1918.

Application filed June 6, 1917. Serial No. 173,210.

To all whom it may concern Be it known that I, J EAN MARIE BAUnnNs, J12, a citizen of the United States, residing at Port Arthur, in the county of J efl'erson and State ofTexas, have invented new and useful Improvements in Valve-Operating Mechanism, of which" the following is a specification. I

,My invention relates-to valve'operating mechanism and has for its primary object to provide a simple and eflicient meansfor operating a valve at a distance.

A further object of my inventionis to provide a valve operating mechanismwhich can be easily attached to the valve stem of an ordinary valve. I i

A further object of theinvention is to produce a guide revolubly mounted on the hub of a chain carrying. sprocket wheel which is secured to the stem of. the valve to be operated, said guide being in the nature of a casting and having a flanged hood at one of its ends arranged over the sprocket wheel for retaining the chain in engagement v therewith and having its other end weighted and provided with a yoke through which the leads of the chain pass.

With these and other objects in view which will be hereinafter fully described and particularly pointed out in the claim,

- the invention consists in the novel construction and arrangement of parts illustrated in the accompanying drawings forming a part of this specification, in which Figure 1 is a sectional side elevation of a valve to which an operating mechanism embodying my invention is attached.

Fig. 2 is a front elevation of the same.

Like characters of reference indicate like parts in the various views.

In the drawings 1 designates a valve body. The valve body has a passage 2 leading therethrough, and a partition 3 extends across said passage 2 and has an aperture 4 therein which connects portions of the passage lying above and below the partition. That portion of the partition 3 which has the aperture 4 therein lies parallel to the passage and has a valve seat 5 formed about the aperture 4. An apertured boss 6 is formed on the valve body in axial alinement with the valve seat 5, and a flanged. sleeve valve seat 5 and has screw threads 9 formed at the inner end thereof. A valve stem 10 is screw threaded into the screw threads 9, and has a valve 11, mounted at its inner end, which isadapted to engage the valve seat 5 when the stem is screwed to its inner posi tion and to close the valve thereby. The stem 10'extends outwardly from the sleeve 7, the sleeve 7 having a packing nut 12 screw threaded upon its outer end to prevent leakage between the sleeve and valve stem. The stem 1O is formed angularly in cross section near its outer end, as designated at 13, the inner end of said angular portion having an outwardly facing shoulder 13, and the extreme end thereof is screw threaded as designated at 14. The above described construction is well known to those skilled in the art and needs no further description for the presentpurpo'ses except to say that all valves of this construction are usually provided with a hand wheel whichengages the angular portion 13 and is secured thereon by means of a nut screw threaded upon the screw threads 14:.

15 designates a sprocket wheel which is provided with a centrally disposed angular aperture which is adapted to fit closely over the angular portion 13, the inner surface of the web 16 of the wheel abutting the shoulder 13. A hub 17 projects from the outer face of the web, the combined thicknesses of the web and the hub being approximately equal to the length of the angular portion 13. Sprocket teeth 18 are formed upon the periphery of the wheel 15, and a circumferential flange 19 is formed upon said wheel upon each side of the teeth 18, said flanges being spaced from the teeth 18 s0 that a chain 20 may be trained over said sprocket wheel to engage the teeth of the same. 21 designates a guide member which is rotatably mounted upon the hub 17 by an oifset apertured boss 22. The guide is in the nature of a casting, being constructed from a single piece of material. Arms 23 are formed upon the outer face of the boss of 15, and through which the chain passes.

The yoke servesto restriet the chain laters v ally and also to prevent the chain from ji'impingg out of the inelosure of'the flanges 19 and :-re ta;rding the rotation of the-wheel thereby.;-.' 1 p 7 p I Anwasher 27 is mounted upon the screw threaded end 14 vof'the'stem and engages the boss 221m preventit from working ofli of the hub 17 and a nut-28 is threaded. upon the threaded end-11: and clampssaid washer against said-hubli 1 t 1 p o Secured-1- upon the inner flange l9 of the sprocket wheel is a weight 29t This weight a ispreferablyv arcuate informand lies closely ad acent the periphery of its flange, and is so disposed upon the whe'el that when the valve -is shut said Weight tends to keep the valve in* closed position against a ar or vibration, whieh'wou-ld otherwise open the valve? I ,7 In'the preferred 'embodiment of my invens tion that: portion of. the guide member :"21

which;.lies below the boss ;2f2 is heavier than domes: oi th is 1iatent,-n1ay.,pe.. obtained for that portionwhich lies above the-boss,- and as aresult the guide member tends to reitain; itself" in properawe rkin relation with chain-2O which hangs downwardly from the WlZleel -15I Having thus fully described my invention,
